Minerals 101: Copper
Mining Process. Copper is usually extracted using open-pit, or opencast, mining, a surface mining technique used when mineral or ore deposits are found relatively close to the surface of the earth. Ore is obtained by drilling holes and blasting rock which is taken to nearby processing sites to be crushed further. The crushed ore is then ...

Copper Mining and Processing: Life Cycle of a Mine
Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the pre-development steps are complete. Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.

Project Overview
The Resolution Copper deposit ranges from 5,000 to 7,000 ft (1,500 to 2,130 m) below the surface. The deposit's average grade is estimated at 1.5% copper 1. The proposed underground mine is expected to become the largest copper mine in North America, capable of producing up to 25 percent of U.S. copper demand each year.

Copper processing
For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 …
